Java Script Object Notation and JSON Formatter

A JSON formatter allows you to add structure to your data to make it easier to interpret. It not only allows you to fix syntax errors but also lets you view the code in a tree view. With the collapsible JSON formatter, you don't have to worry about fixing any errors in your messy file, since it beautifies your JSON code for you. The tool includes an example of JSON format so you can see how it looks and play with the various elements to learn more about them.

JSON, an open-standard format for data interchange, is a text-based structure that is both human-readable and logically understandable. It's perfect for storing information, as it can be sent and received from servers to applications or browsers without any need for parsing like XML - all it requires is the Json.parse function. Thanks to its serialized nature, you have greater control over the project at hand; also, any JavaScript can be transformed into JSON when receiving it from a server or before sending.

JSON is being widely used today for a multitude of reasons, one being that it is not as verbose as XML. Also, files created in this format are generally smaller and don't require closing tags. The structure may be long and complicated but a JSON formatter can easily take care of any errors or untidy presentation. If manually checking for bugs seems like too much effort because the data is large and messy, our JSON file fixer can alert you to any mistakes so you know what to avoid in the future.

JSON Format - What Is It?

In fact, it is a data exchange format similar to XML, but XML is a markup language whereas JSON is an Object Notation format. Both languages are capable of exchanging data in the same way, but JSON is lightweight, which is one of the reasons it is so popular.

Objects, values of these Objects, arrays, and Booleans make up the format of JSON, so it is quite easy to understand. If you are a newbie and want to practice this format, you can find an example in our tool which will help you to understand.

It is possible to write objects in key/value pairs surrounded by curly braces. The value can be strings, arrays, arrays within arrays, Booleans, or numbers. The key and value are separated by a colon and the pair of key/value is separated by a comma. You can access the value in the object by using dot notation and brackets. This will help you better understand the example presented in the JSON Formatter.

Format And Validator For JSON

The JSON formatter and validator not only fixes any errors in the JSON format, it also allows you to validate it. That way, you will know if the structure is correct or if it needs to be updated.

The Edition

You can change the appearance of the fields for your convenience also you can remove, add or move the fields easily plus sort the arrays and objects for better development. Whenever you accidentally remove code, you can easily redo and undo all your actions.


Easily validate the structure of your JSON format if you have a JSON schema in your file. A JSON schema adds more information and defines your objects better, which is why it is considered a good practice.

Beautifier And Minifier

It will load your file into the tree view automatically and make it readable for you. You don't need to install any third-party apps for this. By compressing JSON data into tree view, you can also minify your code to reduce the size of the file. If you need to modify it, you can reconvert it to tree view at any time.

The Online JSON Formatter Viewer Tool: How To Use It

A collapsible JSON formatter can not only validate, minify or beautify your code, but also fix errors. It is also possible to use the JSON data format tool for learning purposes, so if you want to practice your skills, you have come to the right place. Today's websites require fast data processing, so JSON is the only option. To format your JSON file, follow the steps below:

  1. As soon as you land on the JSON formatter page, a text editor will appear with the title "Enter or paste your JSON" This is where you will be entering the contents of your saved file for better formatting. You can test the tool by clicking the "Example" button in the top right corner of the tool, which looks like the below image.
  2. Alternatively, you can either provide a link to the file by hitting the "Load URL" button or upload it by clicking "Upload File".
  3. Once you've uploaded the file or pasted the code, just click "Process" for the results, which will appear under the tool:
  4. Before downloading the file, you can still make any necessary modifications, such as minifying it, beautifying it, or updating its content.

We have multiple development tools to make sure your JSON code looks its best. Our JSON Beautifier and JSON Editor will give you plenty of options to test your code, while the JSON Viewer is perfect for reviewing it in different styles, like collapsible tree view. With our beautifier you can format your code in the exact way you need it, so you can conveniently change it later if necessary.
